Based on the optimization design, the mathematical model of the control strategy parameter optimization taking the minimum fuel consumption as the objective function is established. Then, taking hybrid bulldozer as an example, the genetic algorithm is used to solve the optimization problem. Through optimization, the fuel consumption reduces 4.1% further more compared with conventional bulldozer under...
In [1] a new concept was developed for the design of hybrid electric powertrains that includes optimization of the component sizes as well as control strategies. In contrast to most existing publications, the approach explicitly considers the conflicting goals of low fuel consumption and high vehicle longitudinal dynamics and the trade-off is quantified. This is achieved by formulating two multiobjective...
Hybrid and Electric Vehicles offer the possibility of fuel saving by regenerative braking, a storage and retrieval capability for energy that would normally be wasted as heat during braking event. This paper focuses on regenerative braking in a parallel-series hybrid electric bus and specifically on how its control strategy can be formulated and optimized. To conduct the study it is necessary to model...
